Guys, Dave's right about the capacitance thing - typical so-called 600 ohm mic cable usually runs anywhere from 30-60 pF per foot, where digital cables run around 8-15 pF per foot.
Several years ago, I was in a band that normally ran sound from stage (me, along with keys/rhythm guitar/lights) and therefore didn't have a snake - got asked to do an outdoor benefit for a volunteer fire group, so I built a snake out of some Belden Datalene, 27 pair data cable and some freebie XLR's, 120 feet long. We were the 4th band on the roster, so I was running sound til then - I initially zeroed the board with all the Hi EQ's at +3, thinking that the long run would probably eat up a fair amount of treble - after the PA cut our heads off, I re-zeroed the board with the HF at -4, and it was STILL plenty bright.
Capacitance has more of an effect on hi Z than low, and I was running all low Z with Whirlwind DI's, but it STILL was unreal how much treble there was.
I still have about 350 feet of that cable saved for wiring the new studio, got the whole spool scrap for $10 just because a fork lift ran over it somewhere near the middle... Steve
